72 Scamp and 440 Work in Progress

'm wiring in my ignition box, coil and other things. Im not trying for the hidden wires but would like whats there to be neat and contained. I struggle with cutting them. You can see I have the coil mounted close to the box, the power wire done have far to go. Also in the photo is my 12v key on power.

Do I dare trim these wires back? Ive always hated pulling a radio to find out someone else had been there and cut the wires so damn short you cant do nothing with them. Thoughts? Attached Images
